So the reverse polarity protection diodes I have on my boards are
already doing this? That's excellent news (I will update the Mankato
Parts List to use the Schottky diodes instead), and probably goes a
long way towards explaining why I haven't had anyone report this
failure yet. Thanks again for doing all this work. Oscar, I still owe
you some 2164 chips. Make sure I have your latest address. :)

Tim (wonders if the 2164 will soon be the most well-documented chip in
our arsenal) Servo
